 When the machine is running at low speed, press the screen. The measured drag pressure will
automatically be added to the equalization, warm-up and cutting pressure.
 Close the clamping elements, set the correct pressure for the pipe, and check to see if the
work pieces are firmly held in the clamping tools.
Stay a safe distance away from the machine. Do not stand or reach into the
machine. Keep other people away from the work area.
 Check to see that the welding surfaces are flat, parallel and axially aligned.
Should the joint surfaces show any misalignment, repeat the trimming procedure. For
best results the workpiece ends should not be mismatched by more than 10% of the wall
thickness and the maximum gap between the joint surfaces no more than 0.5 mm. This
recommendation does not release you from your obligation to observe national welding
guidelines. Clear away any remaining shavings with a clean brush.
CAUTION! Do not touch the trimmed, ready to weld surfaces. Ensure that the
surfaces are free of any and all containments and foreign objects!
